"A perfect medicine for bodies that be sick Of all infirmities to be relieved; This heleth nature and prolongeth lyfe eke."
Probably no one would claim that the phenomena now grouped under the head of hypnotism were unknown before the end of the sixteenth century. They are as old as man, yes, probably older, since we know that some of the same phenomena apply to animals. But the claim might well be made that while isolated facts of this kind were well known, especially in the East, no scientific collaboration and explanation were attempted until this time.
As with all other departments of science, we may trace a gradual development. Astrology of old taught the influence of the stars upon men, which doctrine was accepted by the great physician Theophrastus Paracelsus (1490-1541). This, however, was only part of his belief: the human body was endowed with a double magnetism; one portion attracted to itself the planets and was nourished by them, the result of which was the mental powers; the other portion attracted and disintegrated the elements, from which process resulted the body. He also claimed that the magnetic virtue of healthy persons attracted the enfeebled magnetism of the sick. With this theory of animal magnetism, it was only natural that he should value the use of the magnet very highly in the cure of diseases. This dual theory of magnetic cures, that of the magnetic influence of men on men and of the magnet on man, was prevalent for over a century, and found its latest exponent in Mesmer.
Following Paracelsus, Glocenius, Burgrave, Helinotius, Robert Fludd, and Kircher believed that the magnet represented the universal principle by which all natural phenomena might be explained. This principle, existing as it did in the human body, was an important factor in health and disease. The great chemist Von Helmont (1577-1644) taught more precisely that a power resided in man by which he could magnetically affect others, and thereby cure the sick who were most influenced by it. He published a work on the effects of magnetism on the human frame.
About the same time Balthazar Gracian, a Spaniard, boldly proclaimed his views. "The magnet," he said, "attracts iron; iron is found everywhere; everything, therefore, is under the influence of magnetism.... It is the same agent which gives rise to sympathy, antipathy, and the passions." Baptista Porta (1543-1615), one of the originators of the weapon-salve, had also great faith in the magnet. So effective was his work on the imaginations of his patients that he was considered a magician and prohibited from practising by the court of Rome. Sebastian Wirdig, professor of medicine at the University of Rostock, in Mecklenburg, wrote a treatise on "The New Medicine of the Spirits" which he presented to the Royal Society of London in 1673. He maintained that a magnetic influence took place, not only between the celestial and terrestrial bodies, but between all living things. The whole world was under the influence of magnetism: life was preserved by magnetism, death was the consequence of magnetism.
Maxwell (1581-1640) propagated somewhat the same doctrine. He was a firm believer in sympathetic cures, and assumed a vital spirit of the universe which related all bodies. It was probably from this that Mesmer got his idea of what he called the universal fluid. It would seem, however, that Maxwell was aware of the great influence of imagination and suggestion. He said: "If you wish to work prodigies, abstract from the materiality of beings—increase the sum of spirituality in bodies—rouse the spirit from its slumbers. Unless you do one or other of these things—unless you can bind the idea, you can never perform anything good or great." About the same time, in Italy, Santanelli propagated the theory of a universal fluid. Everything material possessed a radiating atmosphere which operated magnetically. He also recognized, however, the great influence of the imagination.
About the year 1771, Father Hell, a Jesuit, and professor of astronomy at the University of Vienna, became famous through his magnetic cures, and invented steel plates of a peculiar form which he applied to the naked body as a cure for several diseases. In 1774 he communicated his system to Mesmer, the man who, more than any one else, drew the world's attention to the investigation of mental healing. Various estimates have been made of Mesmer's character and he frequently has been condemned. He was fond of display, but it is doubtful if he was more avaricious than most persons who lived before and have lived since. He was evidently honest in his scientific investigations and opinions, and this is our main concern.
Friederich Antony Mesmer (1733-1815) was born at Mersbury, in Swabia, and studied medicine at the University of Vienna. He read freely the books written by the authors already mentioned, and accepted much of their teaching. His originality consisted principally in applying to the sick this universal principle, by means of contact and passes, while his predecessors infused the vital spirit through the use of talismans and of magic boxes. He took his medical degree in 1766 and chose as the subject of his inaugural dissertation "The Influence of the Planets in the Cure of Diseases." In this dissertation he maintained "that the sun, moon, and fixed stars mutually affect each other in their orbits; that they cause and direct in our earth a flux and reflux not only in the sea, but in the atmosphere, and affect in a similar manner all organized bodies through the medium of a subtle and mobile fluid, which pervades the universe, and associates all things together in mutual intercourse and harmony." This influence, he said, was particularly exercised on the nervous system, and produced two states, which he called intension and remission, which seemed to him to account for the different periodical revolutions observable in several maladies.
